RainSmart® Drainage Cell

RainSmart Drainage Cell is made from recycled polypropylene and is inert to soil borne chemicals and bacteria. RainSmart cells shallow and effective drainage profile helps landscapes to make use of mature plants on roof gardens that need soil depth and water retention properties. High summer temperatures can cause thermal expansion in concrete and can cause waterproofing to crack. The unique design of the RainSmart Drainage Cell system and void properties helps this heat to escape, reducing the risk of cracking and so enhancing the life of buildings. This product is environmentally friendly, made from selected recycled polypropylene that recharges the groundwater table through the principle of infiltration when used on any natural ground surface. Deck loads are reduced, weighing only 3.2 kg/sqm compared to 250 kgs/sqm of gravel for the same effective drainage. RainSmart Drainage Cell provides a cost-effective and easy to install choice over alternative and traditional aggregate drainage layers used in retaining wall applications. It will reduce the thickness by up to 75% owing to the high void ratio of the RainSmart cell. It is also a lot simpler and faster to install, allowing large areas to be prepared for backfilling without the need to import different aggregates (backfill and drainage aggregate) into the same backfilling process.
